SOLE-EDGE BURNISHER.

Application filed November 24, 1926.` Serial No..150,494.

The invention relates to improvements in machines and vdevices 'for polishing the edges of shoe soles by applyingwax thereto with a heated iron, and it is one ot the most important objects ot the invention, to provide a new land improved biirnisher which i'nalres use of liquid wax, inand,to the sole edge being burnished. d

Another object is to provide an electrically heated burnisher of novel form, so constructed that a heating unit which has been burnt out, may be readily removed and a new one substituted.

Yet another aim is toprovide a burnisher in which unique provisionis made for removing` one burnishing tip and substituting another.

Another aim is to in which a panel for a rheostat, controlling the lcurrent to :the electric heater, forms part of la casing which contains the greater part of the movable burnishing member, 'saidcasing also containing ypart-s of the rheosta., portions of current-conducting wires, land means torconducting wax from areservoir 'to a wax-conductingport of `said.,burnishing member, a very simple and compact arrangement being thus elif'ected, in which practically all working parts are housed and protected. y

. Yet another object is to v provide a novel attachment for burnishing shoe soles, of suoli nature that it may be quickly and easily attached to a finishing machine ot well known forni.

In the drawings above briefly described, 15 designatesa vertically elongated, rigidly supported casing having an opening 16 in view showing` a different drive which may be employed for itsv lower end,the front wallet said casing being preferably formed from Aupper and lower sections 17 and 18, secured tothe body portion of the casing by screws or the like i i 19. The upper section 17, in the present d isclosure, forms the panel of a i'heostat, the' swingable arm of this rheostat beingdisclosed at 20, its contacts at 21, and its resistance coil at 22, this coil and Vcertain other parts such as binding posts of the rheostat,

being continedY within the upper portion of the casing 15.

A burnishing member23 is mounted `for oscillation within the casing 15, upon an appropriate horizontal axis 24, and the lowerv end of said member which performs the burnishing operation, projects Y through the opening 16. vAny desired means maybe employed for oscillating this member`23.-

The member 23 consists of an upper body section 25 and-a lower, removablesectionor burnishing tip 26, and these parts are preferably ,constructed and related as shown. The lower end of the upper section'25 has a ver.

tical bore 27 formed therein, said'bore being open at its lower end but closed at-itsjupper In the upperend, otthis bore, ,21,11 inico ' the like 29, said block being provided with Vjects downwardly from and sulating block 28 is secured by a screw or a pair of contacts 30 which are exposed at its lower' end and being provided with suitable means such as the screws 31, for connecting current-conducting wires 32 and 33, with the upper ends of these contacts. 1n the present showing, wire 32 is electrically connected with the swingable arm 2O of the rheostat, wire 33 passes out of the casing for connection with a source of current, and an companion wire 34, is connected to one of the endmost contacts 21 of said rheostat.

Removably positioned in the bore 27, under the insulating block 28, is a second insulating block 35 whose upper end is provided with contacts 36 removably engaging the 'contacts 30. An electric heater 37 prois carried by the insulating block 35 and this heater may well embody the core 38 integral with the block 35, a resistance element 39 around the core and connected with the contacts 36, insulation 40 around said resistance element,vand

a. metallic, protecting casing 41 around the insulation. This heater 37 projects downwardly through the lower portion of the bore 27, which portion is unoccupied by the blocks 28 and 35, and passes out of the open lower end of the bore. Thus, if the heater' should need replacing or repairing, it is an easy matter to grasp its lower end and pull it vdownwardly out of the bore, at which time the contacts 36 disengage from the conf tacts 30.

Preferably, the body section 25 of the member 23 is vertically divided in a 'plane between opposite sides of the bore 27, providing a front section 42, held normally in place by suitable means such as screws 43. Villen these screws are removed, after lirst removing the front wall section 18 of the casing 15, access is given to the screws 29 and 31. Thus, these screws may be removed to permit removal of the block 28, if any repairs or replacements should, be necessary.

The burnishing tip 26 has its lower end formed with the usual groove 44 for engagement with the edge of a sole or shank, and the upper end of this tip is provided with an integral attaching shank 45 of tubular form. This shank is snugly, yet removably received in the lower portion of the bore 27 and it surrounds the heater 37. When this heater is-as long as herein disclosed, or substantially this length, the tip 26 is also recessed for'its reception, as indicated at 46,. ConductingV of current through theheater 37, through the instrumentality of the rheostat, will cause effective heating of thevburnishing tip 26, and the extent of lsuch heating may'of course be controlled by setting the rheostat handle 2O in contact with any selected one ofthe contacts 21.

Whenever desired, the tip 26 may be downwardly removed and another tip substituted, and for the purpose of holdingany tip in operative relation with the member 23, I4 provide suitable means such as a spring detent 47 engageable with a recess 48 in the shank 45. At its upper end, this shank may be beveled-at 48 to effect release of the detent 47 when the shank 45 is upwardly forced into the bore 27.

Novel provision is made for supplying liquid wax to the tip 26, of the color necessary for either tan or black shoes, or analogous shades.

In the present showing, two reservoirs 50 for liquid wax, are mounted upon the upper end of the casing 15 and are connected by fiexible tubes 51 (preferably metallic tubes) with tubular nipples 52 which rise from the body section 25 of the burnishing member 23, said tubes 51 being within the upper portion of the casing 15. The nipples 52 communicate with ports 53 formed longitudinally in the body section 25 of the burnishing member 23, and the lower ends of these ports are in communication with additional ports 54 within the tip 26, said ports 54 bran'ching from another port 55 which opens into the groove 44 of said tip. In the present showing, the lower end of the section 25 is formed with tubular nipples 56 snugly, yet removably received in sockets 57 in the tip 26, so as to establish a wax-tight connection between the sections 25 and 26 of the member 23. The lower ends of the ports 53 are provided with regulating and cutoff valves which may well be in the form of screws 58. By adjusting these screws as occasion may demand, the flow of wax from one or the other of the reservoirs 50 to the groove 44q may be "controlled, and both ofthese valves are closedwhen one tip 26 is to be removed and another substituted. Olviously, the liquid wax supplied to the tip 26 will be applied effectively by the latter to the sole and consequently the latter will be effectively burnished.

Preferably, the tip 26 is provided with a front section 26a held in place by a screw 26b and removable to permit cleaning of ports 54 and 55 whenever advisable.

Any desired provision may be made for lubricating all movable parts and numerous details may be resorted to in the construction of the dxevice. The body section 25 of the member 23, is provided in the present disclosure, with bosses 59 and 60 through which the pivot 24 passes, and the latter is in the form of a screw which may be removed when the front section 18 of the casing 15 is detached, thus permitting easy removal of the burnishing member 23 should this be advisable for any reason. The bosses 59 and 60 preferably abut the rear and front wallsk of the -casing 15 respectively, and I prefer to provide stabilizing ribs 61 and 62 on the lll() 'llo l roller type.

cam groove 66 receiving a roller 67 on the f member Q3, so that upon rotation of saidV Y, wheel, said member will be oscillated.

member 23 and the wall section 18'respectively, the rib 61 slidably contacting with the rear wall of the casing 15, while the ribs V62 slidably engage the front side of the within the casing 15, said wheel being carried byl a shaft 64 which projects rearwardly from said casing, through an appropriate bearing 65 which may well -befof a. ball or The wheel 63 is formed with a In Fig. 11, the member 23 is of slightly different design at its upper end, and a different type of cam 63a is provided to move said member in one direction, justable spring 68, being usedto rock said member 23 in the other direction.

In Fig. 12, I have illustrated the fact that bevel gearing 69 may be employed if desired for transmitting motion to the cam shaft 70, Vfrom a right angularly disposed driven shaft 71. Other' forms of means for oscillating the burnisliing m-ember 23 and other ways of driving such means, could be shown, vbut those herein disclosed will suiiice to illustrate that I such details. v

For 'mounting the casing- V15 or any suitable supporting` means which might be employed in lieu of said casing, in forms of construction other Vthan that herein disclosed, suitable provision may be made. In Figs. 1 and 2, two bracket members 72 are shown, disposed in spaced parallel vplanes and secured at their front ends to the casing 15, while their lower ends rest upon the usual parallel, horizontally disposed tie-rods 73 of a. finishing machine 74, the latter being of well known construction. The bracket members 72 are secured to the rods 73 and for this purpose I preferably employ bars 7 underlying the rods 73 and bolted at 7 6 to the lower ends of said bracket members. T he rear ends of these bracket members may jointly carry a bearing 77 for the rear end of the shaft 64, and I prefer to provide this shaft with a flanged pulley 78 driven by a belt 79 from a pulley 8O on the usual drive shaft 81 of the machine 74. yIf desired, a clutch (not shown) may be utilized for either connecting the pulley 8O with or disconnecting it from the shaft 81 so that the burnisher need not necessarily operate when the shaft 81 is driven to actuate other parts of the finishing machine.

In Fig. 13, I have shown a special stand 83 for the casing 15 and have illustrated a driven shaft 84 carried bysaid stand for driving the shaft 64 or somel equivalent shaft of the burnisher through the instrumentality a` coiled, adf am not restricted as to Aing having an opening latory arm mounted in said casing and hav-v ofia belt 85 and appropriate pulleys, or other desired driving connection.
